Geotecnologias aplicadas ao monitoramento de queimadas e incêndios florestais no estado do Acre, Brasil

The adverse environmental events that occurred in 2005, such as the drought that hit several cities in Acre State, brought a great concern to the state government regarding the monitoring of extreme climatic events. In this way, the State Secretariat for the Environment (Sema) has made efforts to consolidate a government program that allows better management of the risks of natural disasters in the State and greater agility in response processes and actions. The monitoring carried out at the Hydrometeorological Monitoring Unit for Extreme Events aims to monitor and map hydrological events and follow daily precipitation, hot pixels, fire risk, air quality, river levels, temperature and wind speed. This information is to support decision makers to minimize the effects of the disasters faced by the population in the period of droughts and floods. From the data generated by the data collection platforms (PCDs) we issued daily and monthly reports as well as technical notes, seeking to inform about extreme events. Through the use of geotechnologies it is possible to map, quantify and perform spatial analysis of hot pixels and fire risk in the state. Analyzes of geospatial data and satellite imagery facilitate locating and mapping hot pixels and their trend over time, an important tool to support environmental agencies and local institutions.
